T0 all whom t may concern.'

Be it known that I, ALFRED J. SWING, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Machines forCutting Perforated Music-Sheets, of which the following is aspecication.

My invention relates to means for controlling selectively a series of,punch members operated through an intermittent feed of a master sheet,relatively, with the reciprocation of the punch members in themanufacture of music records. v

The object of my invention is to provide ing a music record for amusical instrument,

having a series of punches, withreciprocating means for operating saidpunches, and means for selectively controlling the operation of saidpunches coacting with the master sheet, intermittently fed relative tothe reciprocating means. H

Another object of my invention is to provide a machine for perforatingsheets, having a series of punches, with reciprocating means foroperating said punches, and selector means interposed between saidreciprocating means, and a master sheet intermittently fed, relative tosaid reciprocating means for ycontrolling the actuation of said punches,said selector means being guided in a direct path between saidreciprocating means and master sheet, with one end thereof adapted toreciprocate with said reciprocating` means.

Another object of my invention is to provide a machinefor perforatingsheets having a series of punches, with reciprocating means foroperating lsaid punches and selector means cordinate with leach `of thepunches of the series and interposed bea machine for perforatingsheetsin prepar-` machine, embodying the principles of my invention.Fig. 2 is a section on line 2, 2, Fig. l. Fig. 3 is a perspective viewof one end of the roll for feeding the paper to be perforated. Fig. 4 isa partial top plan view of the :machine` with` certain parts removed,and in which the latter dimensions have been exaggerated for the sake ofclearness.

A represents the sheets to be perforated, passinoV over a roller B, andabove the punchblock ,and fed by means of the feed roll D. The roll D,upon one end thereof is provided with a ratchet wheel E.

eV represents a pivoted` arm, carrying a pawl e', pivotally connectedthereto and engaging with the ratchet wheel E. rlhe arm e is connectedto an eccentric link F, said eccentric link being connected to the maindriving shaft G. Said shaft is driven from any suitable source. Thus, byeach rotation of the shaft G, the arm e and pawl c will be actuated andcause an intermittent partial rotation of the roll D.

62 represents a check pawl, adapted to engage with the ratchet wheel E,to prevent reverse movement vof the roll D. The roll D, at each endthereof, is provided with a series of arms H, each pivotally connectedand having a roller 71. engaging with a stationary cam J. The arms H arenormally held or maintained in contact with the cam surfaces by means ofthe springs 71.. The cam J is provided with a radial surface j and acylindrical surface j', connected by the curved surfaces jg, to operateor swing said arms H, as the roll D revolves, moving the arm to and fromthe periphery of the roll to grip the paper or sheets and feed the sametherewith. Thus, when the rollers 7L pass over the cylindrical surface jthe arms will be swung to engage and grip the sheets between the armsand periphery of the roll D, and when the rollers pass over the surfacej, they will be swung to a released position, as shown in Fig. 2. Thisconstruction of gripping means maintains the sheets smoothly over theperiphery of the roll with accuracy of feed, eliminating any creasing ofthe paper or looseness between the several sheets and prevents anybuckling or distortion. Such feed is very essential in the operation ofperforating machines, simultaneously perforating a number of sheets, asall sheets should be the eXact duplicate and to correspond relatively tothe master sheet for producing a record for musical instruments.

The shaft G is provided with the eccentrics K, connectedby links 7s, toa crossplate L, said plate is mounted in suitable guides andreciprocated vertically.

nfl represents a series of punches slidably mounted in the guides N,coperating with the punch block to perforate the sheets A, one punchmember being provided for each line of perforations desired in thesheets, and in number representing the various keys of the musicalinstrument. Each punch member M is provided with a stop lug m, adaptedto engage upon a reciprocating bar O, the said bar being normally heldin an elevated position by means of a series of springs 0. By thisarrangement, it will be seen, that after each operation of the punches,the bar O will serve to automatically raise the same, until the stoplugs m engage the under side of the upper guide N. The cross-plate L isprovided with a bar l), provided with slots, into and through which theselector bars Q, respectively project and form a sliding bearingtherewith. Each selector bar Q is provided with a block Q, having anotch Q', adapted to engage with the upper end of a relatively alinedpunch-member M, when the selector bar is in operative position. This endof the selector bar is adapted to reciprocate with the cross plate L,but in normal position the block Q is out of alinement with itsrespective punch member, and therefore will not actuate the same on thedownward travel of the cross plate L.

Q2 represents a lug projected from each selector bar, adapted to engageagainst the cross-bar R, fixed to the oscillating levers r, saidoscillating levers being suitably pivoted to the frame of the machineand preferably one lever is employed upon each end of the series ofpunch members.

r represents a link pivotally connected with the oscillating lever 11 atone end, its opposite end being connected with an eccen tric r2, fixedupon the shaft Gr, to relatively actuate the lever 7", with thereciprocating movement of the cross-plate L, to return the sector barsto their normal position.

Q3 represents a spring, one end of which is fixed to a respectiveselector bar, its opposite end to the guide plate Q4, said guide-platebeing provided with a series of slots coincident with the selector barsand through which said selector bars respectively project.

-This guide plate Qt also serves to maintain the alinement of theselector bars, relative to their punch members and also relatively toeach other. Y

U represents a perforated master sheet adapted to be fed over the guidebar T, and over the feed roll V, and between said roll and the roller V,into the receiving tray V2.

The roller V is fed substantially the same as the papel' feed roll D,and likewise provided with a ratchet wheel.

o2 represents an arm pivotally connected upon the shaft of the feed rollV, and to the shaft G, through the linlr 'U' and eccentric o. y y

'v3 represents a pawl pivotally mounted upon the arm o2, adapted toengage with the ratchet wheel, whereby an intermittent feed is impartedto the master feed roll V, relatively with the reciprocation ofthe/cross plate L.

The arrangement of feed and cross plate reciprocation is such as to feedthe record sheet A, and master sheet U simultaneously upon each upwardmovement of the cross plate, and after the selector bars and punch havereturned to normal.y position.

The opposite ends of the selector bars Qy are provided with the plungerss slidably mounted within the guide plate s, and relatively alined witha series of orifices t, formed in the guide plate T.

S .represents a flexible strap interposed between the forward andrearward ends of the selector bars Q, adapting the forward end to yieldor swing vertically with the reciprocation of the cross-plate L.

The master sheet U is fed so that each horizontal line of perforationsalines with the orices t, to enable the selector bars when released fromtheir' forward position by the oscillating lever r, to move rearwardlyand permit the plunger ends s, to pass through such alined perforationsof the master sheet open to the orifices t. This action will cause theblocks Q of the selector bars to aline with the punch members of allsuch selector bars as have been permitted by a given line ofperforations iny the master sheet, to project into the orifices t. Theremainder of selector'V bars engage an unperforated portion of themaster sheet, and are maintained in their normal position with the punchblocks Q, out of alinement with the punclrmembers M. A downward movementof the cross plate L will actuate the punch members whose respectiveselector bar has engaged through the relative perforation in themastersheet'permitting the punch blocks of such selector bars to bebrought between the cross head and punch member.- Upon an upwardmovementV of the cross plate L the selector bars are simultaneouslywithdrawn from the perforations of the master sheet and moved to normalposition by the cross bar R and its lever and pitman mecha# nism andwith an intermittent feed of both master and record sheets operating`during the upward movement of the cross plate L, for a second operation.

As illustrated, the springs Q3 are employed to impart rearward movementto the selector bars when released by the cross-bar R.V

By this construction of selector bars interposed in a substantiallyhorizontal plane and in iiXed guides between the master sheet and punchcross-plate and of substantially integral construction, no lost motion0r play is had, and the plunger ends Apass freely through theperforations of the master sheet, and Without injury thereto, Which isof material advantage in accuracy of reproduction and in lengthening thelife of the master sheet.

It is obvious that various means or forms may be employed forintermittently feeding the master and records sheets relative With thereciprocation of the punches and actuating mechanism, but theconstruction herein shown is merely illustrated as a means for producingintermittent feed, it being obvious that various Ways may be employedfor accomplishing the same result. The same can also be said as to otherdetails of construction, illustrated and described herein, Which may bevariously modified, Without departing from the features of thisinvention, and I do not Wish to be limited to such construction, exceptas specifically set forth in the claims.

Having described my claimz l. In a machine of the class described, aseries of perforator members, operating means for said perforatormembers, a perforator functioning member interposed between saidoperating means, land each perforator member, a master sheet, areciproinvention, I-

cating'inger for each perforator member cooperating vvith the mastersheet to selectively control its respective perforator member, andiieXibly connected to its perforator functioning member, and means forreturning the parts to their normal position.
